According to regional health authorities, more than 4 confirmed cases of cholera per week are being reported in Kerala State of India, mainly in Thiruvananthapuram District. More than 16 confirmed cases of cholera, a significant increase over average incidence, have been reported since late May 2024 in Kerala State. The outbreak has yet to peak but risk to travelers is minimal.
A Cholera vaccination should be considered for aid and refugee workers and medically vulnerable persons going to affected areas and for travelers visiting friends and relatives in these areas. Travelers, regardless of vaccination status, should observe strict food and beverage precautions and hand hygiene (frequent, thorough handwashing), and carry empiric antibiotic therapy (azithromycin) and oral rehydration solution (ORS) for self-treatment if any moderate-to-severe diarrhea develops. Travelers who develop watery diarrhea should ensure adequate intake of clean water and avoid high sugar (high osmolality) beverages. In case of severe, watery diarrhea, oral rehydration (ideally with an ORS) should be considered if oral fluids are tolerated.
